Higher-order aberrations increased after SMILE for myopia

Small incision lenticule extraction was associated with significant increases in higher-order aberrations in a cohort of patients undergoing the procedure for myopia.
The aim of the prospective study was to compare refractive results and higher-order aberrations in a cohort of 86 patients with high myopia or mild to moderate myopia. The study included 165 eyes that underwent SMILE.
Clinicians followed patients at 1 day, 10 days, 1 month and 3 months.
Spherical equivalent changed from –7.16 D ± 0.93 D preoperatively to –0.2 D ± 0.37 D at 3 months after the procedure in the higher myopia group, while it changed from –4.34 D ± 0.97 D to 0.01 D ± 0.19 D during that same duration in the mild to moderate group (P < .05). In the higher group, a spherical equivalent within ±0.5 D occurred in 87% of patients, while a spherical equivalent within ±1 D was reported in 95% of patients. For patients with mild to moderate myopia, 98% were within ±0.5 D and 100% were within ±1 D.
Other findings showed that 20/20 uncorrected distance visual acuity rates were 77% in the higher myopia group and 98% in the milder group. For corrected distance visual acuity, the rates were 98% in the higher group and 99% in the milder group.
Significant increases were reported for total higher-order aberrations, third-order coma and fourth-order spherical aberrations. – by Rob Volansky
